PATENT FFICEO JOHN o. O. snARLE, OF'cnvorNNAjrr, OHIO.

CAR-H EATER.

SPECIFICATION forming part of Letters Patent No. 304,867, datedSeptember 9, 1884.

Application filed November 10, 1882. (No model.)

i/'o all whom t may concern,.-

Be it known that I, JOHN Q. C. SEARLE, a citizen of the United States,residing at the city of Cincinnati, in the county of Hamilton, in theState of Ohio,have invented certain new and useful Improvements inRailwayar Heaters, which are fully set forth inthe followingspecification, reference being had to the accompanying drawings, inwhich- Figurel is a vertical transverse section of a heater having myimprovement-s. Fig. 2 is a bottom plan view of the ash-chute attachedFig. 3 is a top plan view of the same. Fig. 4 is a plan view of thelocking-ring which holds the ash-chute from turning.4 Fig. 5 is adetailed vertical front and rear section showing the draftopening of theash-hopper and its protecting-apron. Fig. 6 is a cross-section taken onthe line xm, Fig. l, showing a top or plan view of the ash-hopper withthe grate removed.

The same letters denote all the figures.

My invention relates to railway-car heaters constructed on the samegeneral principle 'as the same parts in that shown in Letters Patent No.236,849,

granted to me January 18, 1881; and it consists, partly, in such aheater provided with an aslrchute separately removable from -below thecar; partly in an air-fine between the ash-chute and the surroundingpart of the cai-hoor, and partly in the several devices and combinationsof devices which will be fully set forth hereinafter, and definitelypointed out in the claims, the object being to promote the durability ofsuch heaters, safety in the use of them, and facility in making repairsand changes without removing the heater or disturbing the arrangementsofthe car.

In the drawings, A denotes the outer wall of that part of the heaterwhich surrounds the hre-pot; A, the inner wall; A2, the hre-pot, and Bthe hot-water coil. The outflow-pipe of the coil is provided with aglobe-valve, B',

for the purpose of regulating the outflow of hot wat-er, andconsequently the temperature of i the water in the pipes which passthrough the car. rIhis device will form part of the subject of anapplication for patent which I intend ling shortly. The upper part, A,of the drum of the heater is separate from the part which surrounds thefire-pot, and is detachably aflixed toit by screw-bolts or othersuitable means, so that it canbe readily taken off, and the hot-watercoil taken out or put in. By

'taking out the coil the heater can be used as a radiator or ordinarystove. It has at the top three apertures, a", arranged, respectively, tothe right and left and rear of the center, so as to adapt it todifferent arrangements of the coil according as convenience may demandan outlet on either side or at the back of the heater. There are alsothree corresponding inlet-apertures, in the lower section of the drum,for the entrance of the coil according to its arrangement in the heater.Each of these six apertures is provided with a pivoted cap, ai", or anequivalent cover, for closing it when not in use. Of course, when theheater is used as a radiator only all the apertures are closed. rlheash-hopper C has in its front a draft-opening, c, the outer wall, A,having a correspond,- ing opening, a, which may be closed by aslide inthe usual way. The opening 0 is a little Ybelow the upper margin of thehopper; and an permitting them to fall onto the wood-work of the truckasshown in Figs. 2 and 3 of the drawings. It has a hinged bottom, d, bymeans of which it can be readily emptied at any time. It has three lugs,d', projecting laterally from its upper margin, and the heater bottom A5has on its under side as many correspondingly-arranged brackets, a, cachopen at its inner side and one end, the open end of one facing theclosed end of the next in a continuous circuit, so that by turning thechute one way its lugs d will all engage with their correspondingbrackets, and by turning it the other way will all slide out. The chutecan thus be easily and speedily taken out or putin from below the car,so that an injury to it does not necessitate any displacement of theheater. To prevent accidental detaching, a locking-ring, E, is screwedto the under side of the lower flooring, F, ofthe IOO car around theapert'ure through which the l secured to the heater-bottom and extendingash-chute depends. Lugs e project from its inner margin far enough totouch the chute. The chute being attached to the bottom of the stove andthis ring screwed in place, the contact of the lugs e makes itimpossible for the chute to turn, lowing to the unequal convergence ofits sides, so that the chute is iirmly locked in its place. Vhen,however, it becomes desirable to detach the chute, the screws whichaffix the locking-ring to the car-bottom can be readily unfastened andthe ring removed.

Instead of the conoidal form shown in the drawings, the ash-chute mightbe the frustum of a leaning pyramid, and be attached to theheater-bottom by a pair of lugs arranged to engage and disengage withcorresponding brackets by a backward and forward motion, which would bein like manner prevented by the lugs of a locking-plate. The greatestdiameter of the ash-chute is considerably less y than that of theaperture in the upper floor,

F, through which the chute passes, and the opening around the chutebetween floors is closed by a wall, F2, of galvanized iron or othersuitable material, so that there is an air-flue all around the chute,leading from under the car to within the base of the stove. I make smallopenings f in the stove base so that when the car is in motion there isa continual current of air from below the car up into the apartmentcontaining the heater. The chute andthe neighboring Wood-work are thuskept cool, and all danger of firing or charring the floor by reason ofhot ashes in the chute is removed.

The grate and its supports shown in the drawings will be made thesubject of a distinct application.

Vhat I claim as my invention, and desire to secure by Letters Patent,is-

' 1. In a car-heater, an ash-chute detachably downward through the floorof the ear, in combination with a locking-plate detachably secured tothe car-bottom and provided with lugs e, substantially as and for thepurpose described.

2. The combination of an ash-chute detachably secured to theheater-bottom, and a locking-plate, E, secured to the bottom of the carand provided with openings for the air to pass through it, the bottomplate of the heater having no openings for the passage of air throughit, and having suitable attachments for support-ing it above the floorof the car, for the purpose of admitting air to pass up through thebottom of the car around the ash-chute and out under the bottom plate ofthe heater into the car, substantially as specified and shown.

3. The ash-hopper C, having a draft-opening in its wall, and an inwardlyand downwardly sloping apron having no apertures, arranged above andbehind it, substantially as and for the purpose described.

4. In a carheater, a drum provided with apertures for the entrance andoutlet of a hotwater coil, and with means for closing them when not inuse, and having an upper section detachably affixed to the rest of thedrum, for the purpose of making the heater convertible from awater-heater into a radiator, and vice versa, substantially asdescribed.

5. In a car-heater, a drum provided with two or more sets of aperturesfor the entrance and outlet of a hot-water coil, and with means forclosing them when not in use, for the purpose of changing the directionof the coil, substantially as described.
